2 Claims. (Cl. 52-209) The applicant proposes a new method of producing plastic profiled sections for window frames, window sashes or similar constructional moludings, into which -a wooden core is injected. The profiled sections made in this fashion are not more expensive than those worked by hand from solid wood. These latter require subsequent finishing because wood as material never has a uniform structure throughout. The new method of production saves this finishing work.

The dimensions of the wooden profiled sections hitherto used were mostly prescribed by the architects or contractors so that the sections had to be made, so-to-speak to measure. This naturally means production in small quantities and consequently increased costs of production. After comparing these costs of production for profiled sections produced according to the above-mentioned new method of production with those for solid wood profiled mouldings, the applicant sought for some possibility of further saving expense by decreasing the costs of production and found it by a novel construction of the mouldings which is usita'ble in particular also for producing with his cost-saving method.

As, according to the invention,-all profiles of a window are of the same thickness, and moreover all transverse and longitudinal parts of the window sash have the same cross-section and all transverse and longitudinal parts of the blind frame are given the same cross-section, a minimum number of profiles are now sufiicient in the case of windows. According to the invention each window sash profile has a double rabbet selectively for single or double glazing and in the opposite side of the profile a longitudinal groove for forming a whirling or air compensating chamber, the wall of which situated on the outer side is shorter than that on the inner side and the latter carries a coating in the form of an elastic packing strip composed of foam rubber with plastic cover extending around the entire window frame. The post is, according to the invention, of I-shaped cross-section, the cross-piece or flange of which on the inner side of the I is so short that its end edges bear against the packing strip in the longitudinal groove of the window frame profile and the cross-piece or flange on the outer side is so long that it covers the shorter wall of the longitudinal groove on the outer side. The blind frame profile has at the end of its cross-section facing the sash frame profile the same cross-section as one end of the post profile and'in the other outer end a longitudinal groove for receiving a packing composition, and small plastic tubes are inserted which lead from the whirling or air compensating chamber outwards at an incline to just in front of the longitudinal groove containing the packing mass and serve for conducting off rain water.

Finally all edges of all profiles which bear against packings have sealing beads pressed out from the plastic sheathing.

Cross-sections through the new standard profiles are illustrated by way of example in the accompanying drawing, in which:

' FIG. 1 is a cross-section trough the lower cross-piece of a blind frame and a sash frame with the sash closed, and

FIG. 2 is a similar view to FIG. 1 through a post and two sashes, both in closed position.

In FIG. 1 a sash frame of a window is designated by 10 and hinged on a blind frame 11.

The blind frame profile 11 has in the side remote from the window sash a longitudinal groove 12 which rests at the bottom on the sill and is filled with a packing composition to prevent the penetration of driving rain. This groove extends right round the blind frame and also seals against the masonry or the casing. The blind frame profile 11 as well as the sash profile 10 and. also the post or pier profile are kept the same size.

Between the blind frame and sash profiles 11 and 10 a whirling or air compensating chamber 14 is provided which is intended to collect any penetrating rain-water, particularly in the bottom cross-bar of the blind frame profile. For draining off this rain-water, small plastic tubes 15 are let-into the cross-bar of the blind frame which conduct the water downwards and terminate-on the bottom sill outside the packing groove 12. These water draining tubes 15 are watertight-welded to the exterior of blind frame 11 which is advantageously made with a central core of wood shavings and glue and an outer plastic coating. They are provided in a number sufiicient to carry off the maximum quantities of rainwater to be expected.

The window sash profiles 10 have an interior window pane wall with a double rabbet 16, to take single or double glazing. On the side of the profile facing away from the window panes it has a longitudinal groove 17 defined between short outer or outside wall 18 and an inner or inside l-ong wall 19 which is longer than the wall 18. A coating 20 is applied on the wall 19 in the form of a packing strip extending right roundthe window frame. The edge of the blind frame profile which bears against the packing strip 20 when the window sash is closed, has a sealing bead 21 bulging out from the plastic sheathing of the profile and presses into the packing strip 20 composed of foam rubber coated with plastic and seals the crack in a perfect manner. Such sealing beads 21 are provided everywhere where cracks have to be sealed.

As can be seen from FIG. 2, the sash frame profiles 10 are the same as the sash frame profile 10 shown in FIG. 1. The post or abutment profile 13 is of the same thickness as the sash frame and blind frame profiles but of I-shaped cross-section. Both sides of this I-cross-section are inversely the same as the upper end of the cross-section of the blind 'frame profile. Therefore, in combination with the longitudinal grooves 17 in the window sash profiles similar whirling and air compensating chambers to those between the blind frame and window sash frame are also formed here.

All fittings are secured by screws so that-the plastic sheathing is not damaged and there is no possibility of moisture penetrating the profiles.

What is claimed is:

1. A window construction comprising, a blind frame made with an exterior plastic layer with a wood shaving and glue core and having an interior sash side wall with a longitudinal groove formed therealong between an outside laterally projecting frame wall and an inside laterally projecting .frame wall shorter than said outside laterally projecting frame wall, and a sash frame made with an exterior plastic layer with a wood shaving and glue core and having a window pane Wall formed with a rabbet for receiving a window pane and an opposite wall having a longitudinal groove formed between a short outside laterally projecting sash wall and an inside laterally projecting sash wall which is longer than said outside sash wall,

said short outside sash wall being located interiorally of said long outside laterally projecting frame wall and said long inside sas'h wall being located interiorally of said inside short l-aterally projecting fr-ame wall.

2. A window construction comprising, a blind frame with a core of wood composition and a cover of plastic and having an interior sash side Wall with a longitudinal groove formed therealong between an outside laterally projecting frame wall and an inside laterally projecting frame wall shorter than said outside laterally projecting frame wall and .a sash frame with a core of wood composition and a cover of plastic and having a window pane w-all formed with a rabbet for receiving a window pane and an opposite wall having a longitudinal groove formed between 21 short outside laterally projecting sash wall and an inside laterally projecting sash wall which is longer than said outside sash wall, said short outside sash wall being located interiorally of said outside laterally projecting frame wall and :said long inside sash wall being located interiorally of said inside short laterally projecting frame wall and a tube for leading away water connected to the longitudinal groove of said frame and extending through said frame to an opposite Wall thereof.
